Hello everyone.
I should use radiation model in a case in order to set radiation emissivity to the walls. when I run without any radiation model, then I have no problem and I got a very smooth converge. But when I use the radiation model and use P1 or Rosseland, then I got diverge! I try to run without radiation model to have an initial solution, but again I got diverge! I don't know what should I do!! Anybody here knows what is the problem?! Thanks Last edited by asal; February 23, 2013 at 11:48. |

Hello asal,
are you sure that P1 or Rosseland are the best models for your system? Regards
